Search for PAC4SWX or get the full version of Bluebeam, I have both,.
I prefer Bluebeam for dealing with PDF's, it has a lot of control over the quality of the PDF plus you can and stamps, watermarks and you can combine all the drawings into one PDF document with Bookmarks.
PAC4SWX I use for batch printing converting files to dxf and producing edrawing etc.
Note a lot of these task can be done with SolidWorks Task Scheduler which is free, you will need to have a pdf printer installed to use create pdfs.
When I last tried Task Scheduler some time ago I quickly went back to PAC4SWX, as it has far more useful features.
Links to both can be found on the links page of my website.
